Positioner Payload Options

SPS-910 Joystick

The joystick is a two-axis feedback device for manually steering azimuth and elevation axes to a desired position. The joystick containing a pair of potentiometers, one for azimuth and one for elevation. Moving the joystick handle changes the resistance of the potentiometers. The resulting resistance is applied to the servo amplifiers, causing motion of the positioner's azimuth and elevation axes. Right-left motion of the joystick handle causes clockwise and counterclockwise motion, while forward and backward motion causes downward and upward motion of the elevation axis.

Features:

1. Joystick override momentary switch toggles the joystick between override of position mode and automatic mode override. Press and hold to activate joystick in Designate mode; release to deactivate joystick. Press and release to activate Autotrack in Joystick mode.
2. Standby/Designate/Track switch selects Standby, Designate, or Track mode. If the system is in the Standby mode, use this switch to switch from standby to Designate or Track.
3. Type I/Type II selection switch selects between Servo Type. Use the Type I/ Type II switch to select between a non-compensated and a compensated servo loop.
4. High/low joystick gain switch changes joystick gain between high (30°/sec) and low (3°/sec). Use this switch to reduce the sensitivity to joystick motion. The switch is normally used when optics are on an extended focal length and the motion of the pedestal reflects the rapid changes in the image motion, or the switch is used to reduce the sensitivity when the operator is trying to acquire a target.
5. The finger-operated switch activates the Track mode.

Typical Sensors

SPS series positioners support a variety of EO sensors including CCD cameras, long focal length lens, ELSRF, and TIS. CSS doesn not design or manufacture EO sensors.
